PET Scan: A Case Study
A PET (positron emission tomography) scan is a type of imaging test. It uses a radioactive substance called a tracer to identify diseases in the body. By identifying the cellular level changes, PET may detect the early onset of diseases before other imaging tests identify them.PET scan is mainly used to evaluate organs such as brain and heart, most commonly PET scan is used to detect Cancer and evaluation of Cancer treatments. This session with Dr Prafful, Consultant & Head, Dept of Nuclear Medicine & Molecular Medicine gave interesting pointers on PET scan with a detailed Case based review.

Adult Vaccination Essentials
There have been several updates in adult vaccine recommendations since the last set of guidelines were released. One of the most notable: the Advisory Committee on Immunization Practices (ACIP) recommends that the human papillomavirus (HPV) vaccine be given to all amae and females aged 13 to 26. Vaccination is also recommended for males through age 26 who have sex with men and for those whose immune system may be compromised. Other significant changes include: The ACIP now suggests that adults without evidence of prior immunity to chickenpox receive the varicella vaccine. Special consideration should be given to those at high risk for infection or transmission, such as health care workers and teachers Those who are in close contact with people at high risk of infection. Family and others who come in contact with people with compromised immune systems
Role of Group B Vitamins in Health
Group B vitamins, also known as B-complex vitamins, play a vital role in maintaining overall health and well-being. B vitamins are essential for converting food into energy, as they participate in various metabolic processes, such as carbohydrate, fat, and protein metabolism. These vitamins are water-soluble, meaning they are not stored in the body, and a regular intake through diet is necessary to prevent deficiencies. Vitamin B1 (thiamine) helps in nerve function and energy metabolism and is crucial for the proper functioning of the heart, muscles, and nervous system. Vitamin B2 (riboflavin) supports cell growth and red blood cell production, contributing to healthy skin, eyes, and nerve function as well as for the metabolism of amino acids and the formation of neurotransmitters.
Alzheimer’s Day: Insights World Alzheimer’s Day
Alzheimer's disease is a progressive neurodegenerative disorder characterized by cognitive decline, memory loss, and impaired daily functioning. It is the most common cause of dementia, affecting millions of individuals worldwide. Alzheimer's is associated with the accumulation of abnormal protein deposits in the brain, leading to the death of brain cells and the gradual loss of cognitive abilities. Early diagnosis and management are essential to provide symptomatic relief and support for affected individuals and their caregivers, although there is currently no cure for the disease. Ongoing research aims to better understand its underlying mechanisms and develop potential treatments to mitigate its devastating impact on individuals and their families.
Introduction to Neurology
Neurology is the branch of medicine focused on diagnosing and treating disorders of the nervous system, encompassing the brain, spinal cord, peripheral nerves, and muscles. Neurologists specialize in understanding the complex interplay of neurological functions and addressing a wide range of conditions such as epilepsy, stroke, multiple sclerosis, Parkinson's disease, Alzheimer's disease, and neuropathies. Through clinical assessment, advanced imaging techniques like MRI and CT scans, and specialized tests including electroencephalography (EEG) and electromyography (EMG), neurologists work to pinpoint the underlying causes of neurological symptoms like headaches, seizures, movement disorders, and cognitive impairment. Treatment strategies may involve medications, physical therapy, lifestyle modifications, and in some cases, surgical interventions. With the ongoing advancements in both diagnostic tools and therapeutic approaches, neurology plays a crucial role in enhancing our understanding of the nervous system and improving the lives of those affected by neurological disorders.
Health Aging & Assessment
Maintaining a balanced diet, staying physically active, and avoiding smoking and excessive alcohol consumption contribute to healthy aging. Mental engagement through activities like reading, puzzles, and social interactions helps preserve cognitive function. Maintaining social connections reduces feelings of isolation and supports mental and emotional well-being. Adopting stress-reduction techniques, such as mindfulness and relaxation exercises, supports overall health. Prioritizing sufficient and restful sleep is vital for energy levels, immune function, and cognitive health.
